Ruby! Y U SO BEAUTIFUL?

If you put this baby in some file inside config/initializers of your
app, you will be able to do this:

"carrot".a_or_an=>"a carrot""apple".a_or_an=>"an apple"

Yeah I know, it's awesome! I've just thought every instance of class "String" how to do something new.
This is called metaprogramming and this is one of the coolest things I've found out about Ruby. However, don't use my
solution if you have more complex requirements, like support for
acronyms and abbreviations.
